I'm in favor of having roads under the conditions you mention above. I
would also like to suggest that perhaps there is a way to destroy roads
as well -- though i'm not sure how practical this would be.

In particular, building roads in Mountain provinces should be very
expensive but -- on the other hand -- should greatly increase travel there.
